What Kinds of Valves are Used in Petrochemical Industry

Petrochemical Industry Valve


The petrochemical sector is one of the most significant industrial sectors that cannot thrive without the humble valve. The petrochemical industry relies on valves and their components to ensure the safety of their complex processes. A petrochemical facility has thousands of meters of pipelines. Intercepting these pipes are valves, large and small. They play a vital role in regulating the flow of various media. They are mainly used for oil and gas and numerous petrochemicals, from which other chemicals are derived.

The petrochemical industry is massive, and its applications aren’t just limited to oil and gas production. Petrochemical plants are responsible for manufacturing, storing, and transporting various materials. These include gasoline, cosmetics, fertilizers, detergents, synthetic fabrics, asphalt, plastics, and other petrochemicals derived from coal and natural gas. As a result, this industry and the products it makes play an enormous role in our daily lives.

A petrochemical plant is a relatively dangerous place as many of its daily operations are governed by extreme temperatures and pressure. It is why valves are essential for the operation of petrochemical plants. They help to control the temperature and pressure of these materials’ fluids as they move around each plant.


  • It can start or stop the flow of fluids such as hydrocarbons, oil, steam, water and acids.
  • It regulates the flow of fluids in the pipeline.
  • It can control the flow of fluids in channels.
  • Change the direction of the flow of certain fluids in a channel.
  • Regulate the pressure of fluids in a particular process.
  • Protect a piping system from overpressures or back pressures.
  • Filter debris that could be flowing through a pipeline and protect equipment that substantial parts could damage.
  • Protecting the pipelines from mounting pressure. Without valves, the environment in petrochemical plants can become dangerous and prone to catastrophic events.



This valve is mainly used to open and shut the flow of fluids. They are available in a concentric or eccentric design, with a much more compact shape. As such, they have become far more in demand.


Ball valves are your industry-standard valves that are used for on-off applications. In other words, they’re used to open and shut off the fluid flow. They are generally lighter and more compact than gate valves, which serve a similar function.


Check valves are used in a petrochemical plant to regulate the backflow of fluids in a piping system. Essentially, they help prevent unwanted flows that could damage apparatus such as pumps and compressors.


Globe valves work only in one direction. You can use them to stop and start flow with high precision, which effectively regulates many pipe systems. These valves are often used for oil, fuel, and chemical control and transport in the petrochemical industry. They are designed for a wide range of uses and are simple to service.. In addition, they are designed to ensure leak-proof, bubble-tight seating for thousands of cycles.


Knife gate valves are used to cut through very thick fluids such as petroleum and crude oil, which helps regulate and modulate this material’s flow. However, these gates can only handle a certain amount of pressure, so other gate valves are also valuable to a petrochemical plant, such as slide gate valves.


Also called safety valves, these components are essential for the overall safety of plant personnel and equipment. These mechanical valves help prevent leakage and onsite explosions while preventing hazardous materials from escaping into the environment.


This cylindrical or cone-shaped valve works to either allow or stop the flow. It switches between the “open” and “plugged” positions via rotation. The internal hollow passages will enable the liquid and chemicals to flow in the open place. In the “plugged” position, the valve is rotated to block the hollow internal passages and stop the flow. Since they are high-capacity valves that can handle high temperatures and function best in low-pressure applications, they are often used in petroleum pipelines.


A sliding gate valve is a linear motion valve. Unlike knife gate valves, it is designed to handle dry powders, granules, pellets and other media. It uses a sliding plate instead of the blade in a knife gate valve to stop the flow of dry materials. Depending on the petrochemical industry application, you can use either a knife gate valve or a slide gate valve.


Vacuum relief valves are called “breather” valves because they provide pressure and temperature relief to pipes and tanks. Many areas of the petrochemical industry will result in high pressure and temperature that must be relieved to avoid dangerous explosions, damage, and other consequences.
